'Language' in the Bible

Of these were the islands of the nations divided in their lands, everyone after his language, after their families, in their nations.

The whole earth was of one language and of one speech.

Yahweh said, "Behold, they are one people, and they have all one language, and this is what they begin to do. Now nothing will be withheld from them, which they intend to do.

Come, let's go down, and there confuse their language, that they may not understand one another's speech."

Therefore its name was called Babel, because there Yahweh confused the language of all the earth. From there, Yahweh scattered them abroad on the surface of all the earth.
